Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Continuous updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** The ultra-high molecular weight polyethylene nitrogen-based closed-loop drying/deep devolatilization/mother liquor alkali washing systems, developed independently by Tianhua Institute, have been successfully applied in the A and B production lines for specialty polyolefin materials used in new energy applications at Puyi Jingxin New Materials (Shanghai) Co., Ltd. This development was covered in a special report by CCTV, leaving a significant mark on the Tianhua brand’s presence in the field of new materials. New materials are one of the industries that will receive priority development in China’s 14th Five-Year Plan period. Tianhua Research Institute has kept pace with relevant strategies and market demands by investing early in the key technologies associated with this industry. Thanks to its decades of extensive technical expertise and innovation capabilities in the field of chemical equipment, it has achieved significant breakthroughs in the development of key equipment for strategic new materials such as ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene, as an engineering plastic with excellent properties, is widely used in fields such as medicine and environmental protection. The nitrogen closed-loop drying system independently developed by Tianhua Institute employs a fully enclosed nitrogen circulation process, which not only prevents the risk of material oxidation and dust explosions but also significantly improves thermal efficiency ； The deep devolatilization system, through precise flow field design, reduces the residual volatile content in the product to industry-leading levels, thereby effectively improving the purity and stability of the material ； The mother liquor alkali washing system optimizes the material purification process, ensuring high-quality raw materials for subsequent production. The successful application of these three systems not only demonstrates Tianhua Institute’s technical expertise in the field of new material equipment, but also breaks the monopoly held by foreign companies in high-end chemical processing equipment, providing crucial support for the independent and self-sufficient development of China’s ultra-high molecular weight polyethylene industry. As a leading enterprise in the field of chemical engineering equipment in our country, Tianhua Institute has always taken it as its responsibility to \"support strategic initiatives and promote industrial upgrading\". Leveraging platforms such as the **Research Center for Drying Technology and Equipment Engineering**, continuous breakthroughs have been achieved in various key technologies within the new materials industry. A set of integrated, self-developed, environmentally friendly, and intelligent solutions for key post-treatment technologies has been developed, including crystallization systems, filtration systems, drying systems, pneumatic conveying systems, and devolatilization systems. These solutions have been applied to new materials such as POM, POE, PS, PA, PPO (PPE), UHMWPE, EPDM, EVOH, and AMPS, enabling breakthroughs in related post-treatment technologies. “During the 15th Five-Year Plan period, Tianhua Institute will continue to focus on the core needs of the new materials industry, deepen technological innovation and integration with industrial applications, and use more advanced equipment and reliable solutions to help China’s new materials industry achieve high-quality development, thereby contributing to the goal of building a strong manufacturing nation and achieving the ‘dual carbon’ targets.
